Application filed January 28, 1908. Serial No. 413,045.

Taall whom it may concern Be it known that I, EDWIN E. SLICK, ofPittsburgh, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in Hotbeds, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings,-forming part of this specification, in whichFigure 1 is a top plan View showing a double hot bed constructed inaccordance with my invention; Fig. 2 is a sectional end elevation of thesame on the line 2*2 of Fig. 1; Fig. 3 is a longitudinal section on alarger scale of one of the helical or spiral screws or worms, formingpart of this i11 vention; Fig. 4 is an end view of thescrew shown inFig. 3; Fig. 5 is a sectional side elevation on a larger scale showing aportion of the turning mechanism by which the rotating skids or supportsforming the hot bed are rotated.

My invention relates to storage beds and similar apparatus employed inrolling mills in handling metal bars and similar materials, and it moreparticularly relates to hot beds having means for transferring suchmaterials transversely of their length across the width of the hot bed;i

pleted to a cold state in which they can-,if

desired be handled by hand.

Another object of the invention is to provide improved mechanism foractuating the apparatus employed in carrying the bars across the widthof the hot bed and to provide improved means by which the bars are movedon to the hot bed from the rollers of the delivery table and on to therollers of the receivin table from the rotary supports or ski s, formingthe hot bed.

A further objectof the invention is to pro vide improved means forkeeping the bars in positionon the rollers of the delivery table whilebeing fed forwardly on these rollers to a point opposite the hot bed,and means for retaining and collectin the bars as they are successivelyremoved tom the hot bed, and for depositing the collected bars on therollers ofthe receiving table.

In the drawings, 2, 2, represents the rollers of the delivery tables onwhich the materials are carried from the reducing rolls of a rollingmill or other point of supply to a point alongside of the hot bed fromwhich they are automatically transferred to the hot bed.

The'rollers 2 are mounted on the oppositeoverhanging ends of suitableshafts rotawhich extends between the sheave wheels 6' and 7. which arelocated at oppositeends of the hot bed. The sheave wheel 6 is driven byany suitable type of motor, not shown,

and the wheel 7 is adjustably mounted so as to regulate the tension onthe driving rope 5.

Extending on opposite sides of'the tables formed by the rollers 2 arethe hot beds which are formed of a series of rotating skids 8,- havingmeans thereon for pushing the materials lengthwise of the skids. Theends of these skids are journaled in suitable bearings 9, and on theirouter ends arev spur pinions 10, which meshwith and are rotated by spurgears 11, which are rota-V.

tably mounted on stub shafts 12. Each of the spur gear wheels 11 isprovided with ratchet teeth 13, and on each of the shafts 12 is arocking arm 14. One end of the arm 14 is provided with a pawl 15, whichongages with the ratchet teeth 13 on the wheels 11, the opposite end ofthe arms 14 being connected together by means of links 15', and meansfor adjusting the length of these links is provided by the sleeve nuts16.

One end of the link 15 is connected to a crank 17 on the slow-downgearing 18,

which is connected with the rotary motor 19.

On the outer side of each hot bed formed by the rotating skids 8 arereceiving tables formed by the rollers 20, these rollers being driventhrough bevel gears 21, 22, and line shafts 23, which shafts areconnected through slow-down gearing 24 with tabledriving motors 25.

The rotating skids 8, forming the hot bed,

a are provided on their ends with inclined wings 26 and 27, these wingsbeing'ar ranged to lift a bar from the rollers 2 and 1 cause to slideinto engagement with the root of the threads formed on the skids '8 ateach revolution of the skids. The receiving ends of the skids 8 areprovided with spaced apart encircling guide collars 8 which some as sideguards to guide the metal barsior shapes as they are deliveredlengthwise on the rollers 2, the Wings 26 on this endiof the skids 8being below the plane of the top of the bed formed by the skids exceptwhen elevating the bars in, transferring them sidewise from the rollers2 to the skids 8, The outer ends of the skids are also provided withinclined supports 28, upon which each bar slides when lifted by thewings 27. "'T he lower outer ends of the sup orts 28 have rocking arms29, provided at suitable intervals in the length of the hot bed, thesearms serving as stops to retain and collect'the bars on the supports 28,until such time as it is desired to have these bars discharged upon therollers 20, forming the receiving table. The lower ends of the arms 29are connected together by means of links 30, these lin rs beingconnected to the cranks 31 on the slowdown gearing 32, connecting thelinks with the operating. motors 33 In theoperation of my improvedapparatus, the bars or other materials are delivered ,endwise on therollers 2 froma point of supply, until they are opposite the hot bedformed by the revolving skids 8. As thebars are carried forward on the qrollers 2, they come into engagement with the stop 35 and are brought torest in position to be removed from the rollers 2 on to the skids 8. Theskids 8 are intermittently rotated by the motors 19, through theconnecting ratchet mechanism,'and 'as the wings 26 on the skids 8approach a vertical position, the bars are successively lifted from therollers 2 and slide down the inclined edges of the wings 26 on tov theskids 8. As the skidsrotate, the bars are then fed forwardly across thelength of the skids, and upon reaching the ends of the skids. come intoengagement with' the inclined edges of the wings 27. When these wingsapproach a vertical position, the bars are again lifted and slideforwardly on to the supports 28, the bars preferably being. held at,this point by the stops 29. although these stops may be omitted, ifdesired.

front of the hot bed. Provision for momen-- tarily holding the wings 28and 27 in their vertically upright position is made by means of thesprings 36 which press against thesquare sides 37 on the hubs of thewheels 11, asis best shown in Fig. 5.-

Theadvantage's of my invention will be apparent to those skilled in theart. There are no lifting parts, necessitating the lifting of all of thebars on thetables on the hot bed, in moving them forwardly across thewidth of the hot bed.,. As the bars are moved gradually across the widthof the hot bed by the intermittent rotation of the skids'or supports onwhich these bars are carried, they will be moved forwardly endwise atthe same time. This gives constantly changing points of contact on thebars and prevents the formation of black spots at the points of contactas is the case where the bars do not move lengthwise, while beingtransferred across the width of the hotbed.

The apparatus is simple and is easily kept in-repair. Modifications inthe construction and arrangement of the parts may be made withoutdeparting from my invention as de- The angle of'the thread of therotating skids or screws may be changed as is desired.

I claim:

1. A hot bed comprising in combination,

a series of lengthwise parallel rotary bar supporting and transferringmembers,- said members having screw threads thereon, and means forrotating said members, sa d means havlng spur p1n1ons on the supportmgand transferring members, spur gear 'wheels' meshing with the pinions,ratchet wheels for turning the spur gear wheels, a series of rockingarms having pawls engaging the ratchet wheels and means for rocking thearms to thereby actuatethe supporting 'members in transferring barsacross the width .of the hotbed; substantially as described.
